The two tools serve clearly distinct purposes: feed_list enumerates all feeds with metadata, while feed_changes reports row-level changes for a single feed since the last build. There is no functional overlap, and an agent can easily choose the right tool.

Both tool names follow the same snake_case convention with a consistent 'feed_' prefix followed by a descriptive noun. The pattern is predictable and readable.

Two tools is borderline thin for a data feed server; while list and changes cover core operations, additional operations like fetching a single feed's details or querying custom change ranges would be expected. The count feels under-scoped.

The surface covers listing feeds and retrieving changes for one feed, but notable gaps exist: no dedicated operation to get a single feed's details (relying on filtering feed_list), no historical or custom-interval change queries, and no direct access to the underlying data rows.
